How Windows Are Measured (and Why We Do It On Site)

Curious how window measuring works? Here's why it's a job for the maker, not the customer.

Why measuring is risky to get wrong

A window made to a wrong measurement is scrap — there's no adjusting it after fabrication. That's why the risk should sit with the maker, not you.

What a proper measure involves

1
Measuring the opening at several points, not one
2
Checking whether the opening is square
3
Accounting for the fixing and sealing gap
4
Confirming the sill and reveal condition
5
Noting access and fitting constraints

Why we insist on site measuring

We measure on site rather than working from your numbers — a reputable maker always will, because the consequence of a wrong size is theirs to bear. If someone quotes off your measurements without visiting, be cautious.
